The smallest of the motorized UniSlide Linear Stages with a body width of 1.5 inches, slider length of 1.5 inches and a carrying capacity of 3 lbs. horizontal load. The MA15 can travel up to 10.5" with the 1.5" slider/carriage. The MA15 Series UniSlide is available in 4 lead screw pitches. Recommended step rate is 1000/steps per second. Because of it's light weight, the MA15 Series is ideal for moving small sensors or other light duty applications.

MA15 Series UniSlides are comprised of an aluminum alloy extruded dovetail base with 60 degree opposing V-type ways. An aluminum alloy carriage that runs in the dovetail ways of the base. MA15 lead screws are constrained and supported with pre-loaded Delrin® thrust bearings, which have pre-loaded ball bearings. The lead screw drive nut is a tension adjustable nut made of Delrin providing low friction, and minimal backlash.

UniSlide Specifications – Motor-Driven Assemblies

Factors such as size of the motor, size of the payload, travel distance, mounting direction/plane, etc. effect the actual capability of any assembly. Please contact Velmex Application Engineers to configure a system that will meet your exact requirements.

Basic Dimensions for MA15 Series UniSlide Assemblies

UniSlide Configurations

The basic linear UniSlide is a 1-axis stage. UniSlides can be combined for multiple axes in a wide range of lengths and payload capacities. See Examples for images of various multi-axis UniSlides and combinations that include other Velmex stages.

Options/Accessories

An array of options and accessories is available for the MA15 Series UniSlide Assemblies

Adapter Plates

XY Plates – allow two UniSlides to be converted into an XY motion system. For more specifics and to see the adapter plates in use on a Velmex stage visit the UniSlide Adapters page.

A1500XY Adapter Plate – To mount two MA15 Series UniSlide in XY.

XZ Plates – Allow UniSlide assemblies to be positioned vertically facing in any of four directions. For more specifics and to see the adapter plates in use on a Velmex stage visit the UniSlide Adapters page.

A1500XZ Adapter Plate– To mount a MA15 Series UniSlide to another MA15 Series in XZ.

XZ Brackets – allow UniSlide assemblies to be positioned vertically, facing in any of four directions and perpendicular to the X or Y plane. For more specifics and to see the brackets in use on a Velmex stage visit the UniSlide Adapters page.

A2501XZ Adapter Bracket – To mount a MA25 Series UniSlide to another MA25 Series (6"- 9") or to an A15 Series (6"- 9") in XZ. (The MA25 would be the base horizontal stage. The other stage would be mounted vertically.)B2503XZ Adapter Bracket –To mount a MA25 Series UniSlide to another MA25 Series (over 9") or to a MA15 Series (over 9") in XZ. (The MA25 would be the base horizontal stage.)

B5990TXZ-BK Adapter Plate – To mount two B5990TS Rotary Tables at right angles to each other or to mount a B5990TS to any MA Series UniSlide.

Platform Shelf – A right angled bracket designed to be used with UniSlide® Elevating Tables. However, they also can be used with vertically mounted UniSlide Assemblies to support a payload. The shelf can be inverted depending on the motion required.

Slider Lengths – Varying length carriages (sliders) can be added to all models of UniSlide Assemblies. Choosing a longer slider reduces the standard travel distance. 1.5" is the standard slider on the MA15 Series. Optional lengths available for the MA15 are 2" or 3".

Left-Right Screw Motion (-LR) – This configuration is very useful for applications where two objects must share a common axis of movement. This assembly incorporates two carriages driven by a single right- and left-hand threaded lead screw. When the knob is turned, the carriages simultaneously move toward or away from each other.

Two Independent Carriages (-DS) – a variation on the left-right screw motion UniSlide is one containing two lead screws with control knobs at both ends of the assembly. Each lead screw and carriage operates independently.

Limit Switches – Fixed end-of-travel limit switches are available as an option.

Outboard Adjustable Limit Switches – Mounted on the side rib of Velmex UniSlide Assemblies, these switches can be used to stop travel, provide more stops than the standard two, over-travel a stop point, change speed or be active in only one direction.

Fixed, End-of-travel Limit Switches – These push button switches are fixed on the outside rib of Velmex Unislide Assemblies. They are not adjustable. (Pictured MA15 and MA25 versions.)

Encoders and VRO™ Encoder Readout – For a high resolution position readout an encoder and Velmex's VRO encoder readout can be mounted to most linear UniSlide assemblies. An encoder, mounted directly to the slider gives a true and accurate reading eliminating lead screw and backlash errors. (Not available on all UniSlide models.) SEE: Velmex Controls on the Encoders and the VRO Readout for additional details.

Motorized / Manual Operation– It is possible, using a double shaft motor, to produce a Velmex stage that can be manually operated or motor-driven. A shaft extension accommodates the either a Rogan or standard aluminum knob.

The motor is purchased separately. Customers can mount their own motors, if they chose.

Motors – A variety of motors are available to power Velmex UniSlides, most popular of which is the DC step motor. Gear motors, servo motors and high resolution step motors in both AC and DC can run Velmex UniSlides. SEE: Velmex Controls on the Motors for additional details.

The motor is purchased separately. Customers can mount their own motors, if they chose.

VXM™ Controller – Step motors coupled with a motor controller like the Velmex VXM are a cost effective solution for accurate speed and precise incremental positioning. SEE: Velmex Controls on the VXM Controller for additional details.

Velmex offers a multitude of options and accessories for all its products. Usually an option or an accessory will address your requirements. When it doesn't, we can make custom modifications, including:

• Additional holes or slots. (A drawing is required.)

• Intermediate plates to mount your payload

• Special or in between lengths of the dovetail base

• Lead screw shaft extensions

• Choice of drive nut materials, including brass and Vespel
